Embodiment 1

[0100] When the network device and the terminal negotiate to change the frame structure of the terminal, the terminal may initiate a frame structure change request. For example, see image 3 as shown, image 3 The terminal 100 in is any terminal served by the network device 200 (note that it is any terminal here, that is, different terminals served by the network device can be processed independently), and in step 301, the frame structure currently used by the terminal 100 is not When the requirements are met, send a frame structure change request to the network device 200, the frame structure change request is used to request the network device 200 to change the frame structure currently used by the terminal, and of course it can also be named as another signaling name; in step 302 After receiving the frame structure change request sent by the terminal 100, the network device 200 determines whether to agree to change the frame structure currently used by the terminal 100, an...

Embodiment 2

[0117] In the above embodiments, the frame structure change request initiated by the terminal is taken as an example for illustration. In practical applications, the frame structure change request may also be initiated by a network device.

[0118] When the current frame structure does not meet the requirements of the terminal or the network device, the network device determines a new frame structure for the terminal; the network device sends information for instructing the terminal to use the new frame structure to the terminal. There are many cases where the current frame structure of the terminal does not meet the needs of the terminal, for details, refer to the description of the first embodiment above. The current frame structure of the terminal does not meet the needs of the network equipment mainly means that the load of the network equipment cannot well support the current frame structure of the terminal. For example, when the network equipment is fully loaded and new s...

Embodiment 3

[0123] Figure 7 A structural block diagram of communication between a terminal and a network device in Embodiment 1 of the present application is shown, and for convenience of description, only parts related to the embodiment of the present application are shown. Figure 7 The terminal 100 shown includes: an antenna 110 , a transmitter 120 , a receiver 130 , a processor 140 , and a memory 150 . The antenna 110 is used for transmitting and receiving signals, and is coupled with a transmitter 120 and a receiver 130 . In particular, the transmitter 120 and the receiver 130 may also be combined into a transceiver 160 . The memory 150 is coupled with the processor 150, and is used to store program codes and various frame structures that can be executed by the processor 140, and can also store index tables of various frame structures. The processor 140 is used to execute the codes in the memory 150. When the frame structure currently used by the terminal does not meet the require...

Abstract

The invention discloses a method of flexibly adjusting a full-duplex frame structure. During communication, according to the change of service requirements, a location, an interference situation, a channel quality, load of a network device of a terminal, a full-duplex network device and a half-duplex terminal negotiate to change the frame structure of the terminal, so as to effectively optimize system resource configuration.

Description

technical field [0001] The embodiment of the present application relates to the technical field of communication, and more specifically, relates to a method for dynamically adjusting a frame structure. Background technique [0002] The current wireless communication technology has developed to the Long Term Evolution (English full name: Long Term Evolution; English abbreviation: LTE) system, with the attached figure 1 For example, the existing LTE system includes multiple cells, and each cell has a network device 11 and multiple terminals 12, and the network device 11 sends public control information and data to the terminal 12, and is used to detect public control information and data reference signals. Generally, in order to prevent mutual interference, the network device sends signals to the terminal and the terminal sends signals to the network device using independent resources. This independent resource can be the same time but different frequencies, that is, frequenc...
